We had a wonderful experience renting bikes from Outta Here in Springdale! The owners are extremely friendly, accommodating, patient, and helpful. The bikes are super easy to use and so fun to ride. With parking at Zion being so difficult, renting a bike is the absolute best way to see the park. Outta Here may be a bit farther from the park than some of the other rental shops, but don't let that deter you--the service is so outstanding that it's well-worth the few extra minutes.
